[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This solution provides a telescopic positioning component, which can indirectly drive the annular rust removal liquid box to perform telescopic drilling and pulling operations on the tool during the continuous rotation of the spiral rod, so as to avoid the situation where the tool is not pulled away from the surface of the part hole pin in time after drilling, resulting in the tool being continuously rotated and damaging the ground hole wall and hole bottom, causing the part hole drilling error to increase, affecting the plug-in use of the part after drilling, improving the accuracy of the tool drilling, enhancing the accuracy of the drill mounting block holding the tool for drilling, and ensuring the normal use of the drill mounting block holding the tool for drilling.

[0041] See also Figures 1 to 13 , a CNC precision tool processing fixture, comprising a hollow fixture carrier 1, wherein a telescopic positioning component 2 is arranged inside the hollow fixture carrier 1;

[0042] The telescopic positioning assembly 2 includes a driving motor 21, which is fixedly connected to the inner top wall of the hollow clamp carrier 1, and the output end of the driving motor 21 is fixedly connected to a spiral rod 22, the outer surface of the spiral rod 22 penetrates and is rotatably connected to the inner wall of the hollow clamp carrier 1, and the threaded surface of the spiral rod 22 is threadedly connected with a semi-annular slide plate 1 25 and a semi-annular slide plate 2 26, and the semi-annular slide plate 1 25 and the semi-annular slide plate 2 26 are symmetrically distributed, and the front side of the semi-annular slide plate 1 25 is fixedly connected with a movable plate 1 27, and the rear side of the semi-annular slide plate 26 is fixedly connected with a movable plate 28, and the front end of the movable plate 1 27 and the rear end of the movable plate 2 28 are jointly penetrated and inserted with an annular rust removal liquid tank 23, and the top of the annular rust removal liquid tank 23 is inserted with a drill mounting block 213, and the bottom of the annular rust removal liquid tank 23 is fixedly connected with an elastic force spring 24, and four elastic force springs 24 are provided.

[0043] The two side extensions of the annular rust removing liquid tank 23 are inserted through the inner walls of the hollow clamp carrier 1, and the left and right ends of the top surface of the annular rust removing liquid tank 23 are fixedly connected with hollow fixing plates 214. There are two hollow fixing plates 214, and the two hollow fixing plates 214 are symmetrically distributed. The tops of the two hollow fixing plates 214 are inserted through hollow sliding plates 215, and the bottoms of the four elastic force springs 24 are fixedly connected to the inner top wall of the hollow clamp carrier 1.

[0044] The top of the rear end of the movable plate 1 27 is fixedly connected to a triangular block 1 29, the top of the front end of the movable plate 28 is fixedly connected to a triangular block 210, the triangular block 1 29 and the triangular block 210 are symmetrically distributed, the inner top wall of the hollow clamp carrier 1 is fixedly connected to a triangular block 3 211, two triangular blocks 3 211 are provided, and the two triangular blocks 3 211 are symmetrically distributed and located directly below the hypotenuse of the triangular block 1 29 and the hypotenuse of the triangular block 210.

[0045] The front bottom of the movable plate 1 27 is fixedly connected with a triangular block 4 212, the rear bottom of the triangular block 210 is fixedly connected with a triangular block 5 218, the triangular block 4 212 and the triangular block 5 218 are symmetrically distributed, the inner bottom wall of the hollow clamp carrier 1 is fixedly connected with a triangular block 6 219, two triangular blocks 6 219 are provided, and the two triangular blocks 6 219 are symmetrically distributed and located directly above the hypotenuse of the triangular block 4 212 and the hypotenuse of the triangular block 5 218.

[0046] A spur gear 217 is passed through and rotatably connected to the left side of the rear end of the hollow fixed plate 214, and a rack 216 is meshed with the front tooth groove of the spur gear 217. The outer surface of the rack 216 is inserted into the inner wall of the hollow fixed plate 214, and the right side of the rack 216 is fixedly connected to the hollow sliding plate 215.

[0047] With regard to the tool drill mounting block 213 in the prior art, when in use, the tool body may not be pulled out in time, resulting in the idling blade body performing unnecessary cutting operations on the inner wall and the bottom of the hole, causing the hole to have a larger error after grinding, and the plug-in looseness of the part after drilling, and the part hole cannot be inserted, etc. Moreover, after the drill mounting block 213 clamps the tool for a long time to rotate, the drill mounting block 213 and the tool are exposed to the machining environment for a long time, causing the corrosive particles in the machining environment to adhere to the contact part between the drill mounting block 213 and the tool. The present application sets a telescopic measuring assembly 2. When in use, the output shaft of the driving motor 21 is powered on to rotate, and the fixedly connected spiral rod 22 is driven to rotate, so that the spiral rod 22 rotates to drive the semi-annular slide plate 1 25 and the semi-annular slide plate 2 26 to move downward, and the semi-annular slide plate 1 25 drives the movable plate 1 27 to move downward, so that The semi-circular slide plate 26 drives the movable plate 28 to move downward, and at the same time, the movable plates 1 27 and 28 jointly drive the annular rust removal liquid tank 23 to move downward, and the movable plate 1 27 drives the triangular block 1 29 and the triangular block 4 212 to move downward, and the movable plate 2 28 drives the triangular block 2 210 and the triangular block 5 218 to move downward, so that the downward force of the annular rust removal liquid tank 23 pulls the four elastic force springs 24 to stretch downward to store force, and then the annular rust removal liquid tank 23 drives the drill bit mounting block 213 When the clamped tool moves downward, the clamped tool can be stretched and drilled with shock absorption, avoiding the vibration caused by the rotating friction parts of the tool when the tool drills the surface of the part, resulting in unstable clamping of the drill mounting block 213, causing the drilling deviation of the tool clamped by the drill mounting block 213, reducing the impact of vibration force transmitted by the tool, improving the efficiency of shock absorption transmitted by the annular rust removal liquid tank 23 and the four elastic force springs 24, enhancing the effect of the drill mounting block 213 on stably clamping the tool, and ensuring the normal use of the tool for safe drilling holes.

[0048] Synchronously, the annular rust removal liquid tank 23 drives the hollow fixed plate 214 to move downward, and the hollow fixed plate 214 drives the hollow sliding plate 215 to move downward, so that the hollow sliding plate 215 can perform an extended positioning operation on the drilling depth of the tool, thereby avoiding the unclear depth of the tool drilling the part, which leads to safety problems such as the tool body grinding being blocked after the tool drills the part hole, resulting in the cracking of the cutter head, damage to the blade, and splashing of the part. The control of the tool drilling depth is improved, the accuracy of the tool drilling part holes of different depths is enhanced, the safety of the tool stably drilling the part hole is increased, and the normal progress of the tool clamping and drilling process is ensured.

[0049] When the top surface of the hollow sliding plate 215 further descends to the same level as the top surface of the drilled part, the triangular block 4 212 and the triangular block 5 218 both descend to be flush with the bottom position of the triangular block 6 219, and then, under the action of the continuous downward force of the movable plate 1 27 and the movable plate 2 28, the hypotenuse of the triangular block 4 212 gradually contacts the hypotenuse of the triangular block 6 219 at the front end of the hollow fixture carrier 1, and the triangular block 4 212 moves forward along the hypotenuse of the triangular block 6 219, thereby The triangular block 4 212 pulls the movable plate 1 27, the semi-circular slide plate 1 25 and the triangular block 1 29 to move forward, and the hypotenuse of the triangular block 5 218 gradually contacts the hypotenuse of the triangular block 6 219 at the rear end of the hollow fixture carrier 1, and the triangular block 5 218 moves backward along the hypotenuse of the triangular block 6 219, so that the triangular block 5 218 pulls the movable plate 2 28, the semi-circular slide plate 2 26 and the triangular block 2 210 to move backward, causing the semi-circular slide plate 1 25 and the semi-circular slide plate 2 26 gradually separates from the threaded surface of the screw rod 22, and after the triangular block 1 29 moves forward and the triangular block 210 moves backward to align with the top of the triangular block 3 211, the semi-annular slide plate 1 25 and the semi-annular slide plate 2 26 are completely separated from the screw rod 22. At this time, under the instantaneous pulling force of the four elastic springs 24 after the power is stored, the four elastic springs 24 can pull the annular rust removal liquid tank 23 to retract downward, and then the annular rust removal liquid tank 23 pulls the drill mounting block 213 and the tool in the clamping together. It contracts downward, so that the annular rust removal liquid box 23 can instantly retract and withdraw the tool after drilling, avoiding the phenomenon that the tool drills the hole wall and hole bottom multiple times due to the untimely withdrawal of the idling tool after drilling the part hole, resulting in larger hole groove errors, incomplete part hole insertion, and loose insertion. It reduces the phenomenon that the part hole cannot be used after drilling, improves the accuracy of the tool in drilling the part hole, enhances the aesthetics of the part hole after drilling, and ensures the normal use of the drill mounting block 213 to clamp the tool for stable drilling.

[0050] It should be noted that the hollow sliding plate 215 controls the drilling depth of the tool. After the tool is inserted into the drill mounting block 213 and the drill mounting block 213 is clamped in the annular rust removal liquid tank 23, the spur gear 217 is manually rotated to drive the meshing rack 216 to move upward, and the rack 216 drives the hollow sliding plate 215 to move downward. After the top of the hollow sliding plate 215 and the top of the tool are in the same horizontal plane, the movement of the hollow sliding plate 215 is stopped. When the annular rust removal liquid tank 23 drives the tool to move toward the drilling part of the part, the hollow sliding plate 215 can synchronously move along the side of the part of the specified size, so that the depth position of the tool drilling can be observed, further ensuring the safety and knowability of the tool drilling.

[0051] This solution sets a telescopic measuring component 2, which can indirectly drive the annular rust removal liquid tank 23 to perform telescopic drilling and pulling operations on the tool during the continuous rotation of the spiral rod 22, so as to avoid the situation where the tool is not pulled away from the surface of the part hole pin in time after drilling, resulting in the tool in continuous rotation damaging the ground hole wall and hole bottom, causing the part hole drilling error to become larger, affecting the plug-in use of the part after drilling, improving the accuracy of the tool drilling, enhancing the accuracy of the drill mounting block 213 clamping the tool for drilling, and ensuring the normal use of the drill mounting block 213 clamping the tool for drilling.

[0052] like Figures 6 to 8 As shown, a rust removal component 3 is provided inside the telescopic measuring component 2;

[0053] The rust removal component 3 includes a rust removal liquid inlet valve 31, the output end of the rust removal liquid inlet valve 31 is inserted into the top left side of the annular rust removal liquid tank 23, the bottom of the hollow fixed plate 214 is fixedly connected with a water pump 32, the output end of the water pump 32 is inserted into a drainage pipe 33, the outer surface of the drainage pipe 33 is inserted into the inner top wall of the hollow fixed plate 214, and the top of the drainage pipe 33 is inserted into the bottom of the hollow sliding plate 215.

[0054] A liquid spraying pipe 34 is inserted through the right side of the top of the hollow sliding plate 215 , and the output port of the liquid spraying pipe 34 is directly opposite to the clamping port of the drill mounting block 213 .

[0055] By setting the rust removal component 3, when in use, first manually open the rust removal liquid inlet valve 31, then inject the rust preventive liquid into the rust removal liquid inlet valve 31, and make the rust preventive liquid in the rust removal liquid inlet valve 31 flow into the inner cavity of the annular rust removal liquid tank 23. After the annular rust removal liquid tank 23 is full, manually close the rust removal liquid inlet valve 31 to complete the first liquid injection operation. Then, while the annular rust removal liquid tank 23 and the hollow fixed plate 214 are extended downward, the water pump 32, the drainage pipe 33 and the liquid spraying pipe 34 can be synchronously driven to move downward. At the same time, the input end of the water pump 32 is powered on to start the liquid suction operation, so that the output end of the water pump 32 guides the sucked rust remover liquid through the drainage pipe 33 to the hollow sliding plate 215. After the hollow sliding plate 215 is After the rust remover inside is filled up, it will be transmitted to the liquid spray pipe 34, so that the liquid spray pipe 34 can spray the rust preventer on the clamping part of the drill bit mounting block 213 for lubrication and rust removal, so as to avoid the drill bit mounting block 213 being exposed to the CNC machining environment for a long time, so that the corrosive particles in the machining environment adhere to the contact part between the drill bit mounting block 213 and the tool, resulting in rust on the surface of the drill bit mounting block 213 and the tool, and the drill bit mounting block 213 cannot stably clamp the tool, reduce the occurrence of the problem of failure of the clamping function of the drill bit mounting block 213, improve the stability of the telescopic movement of the drill bit mounting block 213 clamping the tool, enhance the accuracy of the drill bit mounting block 213 clamping the tool to drill parts, and ensure the normal progress of the rust removal and clamping process of the drill bit mounting block 213.

[0056] By setting up the rust removal component 3, the present scheme can indirectly enable the spray pipe 34 to spray the rust inhibitor to the contact part between the drill bit mounting block 213 and the tool for lubrication and rust removal under the action of the rust remover continuously delivered by the water pump 32, so as to avoid the drill bit mounting block 213 being exposed to the CNC production environment for a long time, so that the drill bit mounting block 213 is not seriously corroded due to the corrosive particles in the CNC environment adhering to the fixture and the tool clamping part after clamping the tool for a long time, thereby interfering with the problem of the drill bit mounting block 213 stably clamping the tool, reducing the occurrence of the problem of the clamping function failure of the drill bit mounting block 213, improving the stability of the drill bit mounting block 213 clamping the tool, enhancing the force of the drill bit mounting block 213 to drive the tool to drill holes accurately by telescoping, increasing the service life of the drill bit mounting block 213, and ensuring the normal use of the drill bit mounting block 213 to stably clamp the tool.

[0057] like Figures 9 to 11 As shown, the interior of the telescopic measuring component 2 is provided with an emulsion spraying component 4;

[0058] The emulsion spraying assembly 4 includes an emulsion inlet valve 41 , and the output end of the emulsion inlet valve 41 is inserted through the front end top of the hollow clamp carrier 1 .

[0059] The inner bottom wall of the bottom cavity of the hollow clamp carrier 1 is fixedly connected with a water pump 2 42, and the output end of the water pump 2 42 is penetrated and plugged with a guide tube 43, the outer surface of the guide tube 43 is penetrated and plugged with the hollow clamp carrier 1, and the output end of the guide tube 43 is penetrated and plugged with the annular rust removal liquid tank 23.

[0060] By setting the emulsion spraying component 4, when working, first manually open the emulsion inlet valve 41, then inject emulsion into the emulsion inlet valve 41, and make the emulsion in the emulsion inlet valve 41 flow into the inner cavity of the hollow clamp carrier 1. After the inner cavity of the hollow clamp carrier 1 is full, manually close the emulsion inlet valve 41, and then complete the second liquid injection operation synchronously. At the same time, when the spray pipe 34 sprays the rust inhibitor to the drill bit mounting block 213 and the contact part of the tool, the water pump 2 42 can transport the emulsion in the hollow clamp carrier 1 to the annular rust removal liquid tank 23 through the guidance of the guide pipe 43, thereby realizing the guide. The flow pipe 43 can spray an emulsifier to soften the rust preventive liquid in the annular rust removal liquid tank 23, so as to prevent the rust preventive liquid sprayed from the spray pipe 34 from being unable to effectively adhere to the gap between the drill bit mounting block 213 and the contacting tool, resulting in incomplete rust removal at the clamping gap of the drill bit mounting block 213, causing the drill bit mounting block 213 to squeak when clamping the tool, reducing the instability of the drill bit mounting block 213 clamping the tool when drilling, improving the efficiency of the drill bit mounting block 213 in stably clamping the tool after rust removal, strengthening the rust removal maintenance of the rust remover, and ensuring the normal use of the drill bit mounting block 213 clamping the tool for drilling parts.

[0061] It should be noted that the rust remover process is strengthened, and the water pump 2 42 is continuously conveyed by the water pump 2 42, so that the emulsion is indirectly conveyed to the annular rust removing liquid tank 23, so that the emulsion can soften the hardness of the rust remover, strengthen the rust removal effect of the rust remover, and ensure that the rust remover can penetrate into the gap between the drill mounting block 213 and the tool clamping, so as to ensure the normal rust removal maintenance and stable clamping of the fixture.

[0062] By setting up the emulsion spraying component 4, the present scheme can enable the guide pipe 43 to spray the emulsion to soften the rust remover in the annular rust removal liquid tank 23 under the action of the continuous output of emulsion by the water pump 2 42, so as to avoid the rust inhibitor being unable to evenly adhere to the clamping surface of the drill bit mounting block 213, resulting in poor rust removal and decontamination effect of the drill bit mounting block 213, causing the drill bit mounting block 213 to clamp the tool with low stability, affecting the accuracy of the tool in stable drilling, improving the effectiveness of rust removal and clamping of the drill bit mounting block 213, strengthening the rust removal and maintenance effect of the rust remover, and ensuring the normal progress of the stable clamping process of the drill bit mounting block 213.

[0063] like Fig.12 and Fig.13 As shown, a corner component 5 is provided inside the telescopic positioning component 2;

[0064] The corner assembly 5 includes a cylinder 51, the bottom of which is fixedly connected to the inner top wall of the hollow sliding plate 215, the output end of the cylinder 51 is fixedly connected to a rack 2 52, the top front side of the rack 2 52 is meshedly connected to a spur gear 2 53, and the inner ring wall of the spur gear 2 53 is inserted through the left end of the spray pipe 34.

[0065] By setting the corner component 5, when working, air is firstly ventilated to drive the output end of the cylinder 51 to extend downward, drive the fixedly connected rack 2 52 to move downward, and make the rack 2 52 drive the meshing spur gear 2 53 to rotate, so that the spur gear 2 53 drives the spray pipe 34 to rotate, and then the spur gear 2 53 can rotate the spray pipe 34 to adjust the direction of the nozzle, so as to avoid the occurrence of rust adhesion on the drilling surface of the part due to the long-term weathering of the drilling mouth of the part when the tool clamped by the drill bit mounting block 213 drills the part, affecting the continuous cutting of the tool and affecting the drilling accuracy, reducing the occurrence of the problem of rust on the part interfering with the drilling, improving the effectiveness of rust removal on the drilling mouth of the part, increasing the effect of the tool drilling without resistance, and ensuring the normal drilling of the tool clamped by the drill bit mounting block 213.

[0066] It should be noted that the rotational movement of the spur gear 2 53 is that the spray pipe 34 sprays liquid on the contact part between the drill mounting block 213 and the tool for a period of time, and the rack 2 52 moves down to the position of the tooth groove of the spur gear 2 53, and then the spur gear 2 53 starts to drive the spray pipe 34 to rotate, thereby completing the rust removal process for the drilled opening of the part.

[0067] Usage method: When the present invention is used, the tool is first inserted into the drill bit mounting block 213 of the telescopic positioning assembly 2 and clamped, and then the hollow fixture carrier 1 is inserted into the CNC machining drill, and the CNC machining spindle is started to rotate, driving the hollow fixture carrier 1 to rotate, and then the output shaft of the driving motor 21 in the telescopic positioning assembly 2 is driven to rotate, and the drill bit mounting block 213 is indirectly driven to clamp the tool to perform telescopic drilling and pulling operations and telescopic positioning operations on the parts, and further the rust removal assembly 3 can spray the rust removal agent on the drill bit mounting block 213 and the tool clamping part to remove rust, so that the spray emulsion liquid assembly 4 can spray emulsion to soften the rust remover, and at the same time, the corner component 5 can rotate the direction of the nozzle of the liquid spray pipe 34. After the telescopic measuring component 2 clamps the tool to complete drilling and pulls it out, the ventilation drives the output end of the cylinder 51 to shrink upward, so that the corner component 5 can drive the nozzle of the liquid spray pipe 34 to rotate until it is aligned with the clamping position of the drill bit mounting block 213, and then the output end of the cylinder 51 stops moving. If there are still un-drilled part holes, the above steps can be followed for a cycle. After all parts have completed the drilling task, the output shaft of the driving motor 21 stops rotating and the device stops running.

[0068] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
